Soundsmith Progression: MIMC Star > Sussurro Mk II


Hey Folks--the discount now available on the Sussurro Mk II has me considering the jump from the MIMC Star. Has anyone made the leap and/or done a direct comparison in their own system and, if so, how would you characterize the difference in performance? Thanks for your input.

I have been listening now for one week, and it’s a nice sounding cartridge. I am comparing it to my Kleos and Koetsu Urushi Black. I would say it falls in the middle of both. 
@hcalland ,

The (key) that comes with it.....(it comes in a very nice box, but no manual) is this to be inserted into a USB port? I’m not very computer literate. If so, I assume this will reveal the online manual.

I have no idea what that key is for. I was wondering as well, but just put it in the nice box, and put it away, It doesn’t appear to be a thumb drive.
